To all whom t may concern.'

`Be it knownthat I, LOUIS BINDnn, a citi- AZen ofthe United States, and a resident of Newark, county of Essex, and State of New J ersey, have invented certain new anduseful Improvements in Boxes, of which. the

Yfollowing is a specification.

This invention relates to improvedl box'of :the type usuallyreferred to as a paper box, 'which is usually made from vsheets of cardboard, lexiblein the sheet but, when folded and assembled, having sufficient stiffness to maintain its shape, and

it can be swung back to an open'position and -it will' remain in such openV position without straining the cover or the box.

The invention. is further designed to provide a boxhaving a cover which is easily closed, but which'requires a slight application offorceto jopen lby reason of the attachment of the cover and the construction' of its -free end where it engages the front'edge of the box. Y y

The invention. is illustrated in the accompanying drawing, in which it is necessary to exaggerate the thickness of the walls relative to the size of the box, and in which there is also an exaggeration of the angular position that the lid assumes relativeto the boxfbody when the'lid is shut, this exaggeration being necessary to clearly yillus- `In said drawing, Figure l is a front view Vwith the body of the box broken away at one end, thisview showing the lid open. Y Fig.` 21 is arvertical cross-section of the box shown in Fig. l, and Figure 3 is a view Asimilarto Fig. Y2, with the bottom portion' ofthe box shownin elevation and with the lid shut.)

It will be understood that particular forms offboxes can" be employed other than that shown` and that the parts in themselves can be differently formed and assembled than in the' manner illustrated, but 'in the type of box shown the box comprises a Y front 10, sides 11 and a back 12 formed by folding one strip of cardboard into rectangular shape and suitably securing the corners, usually y.pasting reinforcing which forml of structure is old and lwell known in the boxrtrade.

These, sides are usuallyfformedf from wings that extend yfromv the bottom 13,1and

A srarns rnrnnr .orrion strips thereon, whichpare not shownl and this part ofthe boxso far described I will f -call theV body portion, and-it. sets .intova Y lbase comprising a base sheet llizwhichextends beyond the edges of the body portion andy is agaiiribentinward or upon itself, j preferably at an .anglefasshownvkat `15,\to

form the extending lorprojecting edges,` an inner fold 16,into' which the body portion fits, and a securing strip 17, whichcanbe pasted to hold .theparts in normal position and the base are usually pasted where they abut at the-bottoms@ that they are permanently fastenedtogether.V

fio"v vand also acts asa brace, The body portion The cover is'fusually made tofmatch the bottommportion sothat the box looksl even and symmetricalwhen it is assembled, and in the form'shown'thecover is-sealed tothe base portion, since the top plate 18uhas the 'angular strip 19,:thefinner fold 20 andthe lreinforcing or securing strip 21, andl to further strengthen the lidV I preferablyinsert a bracing sheet 22. AV sheet 23 is placed' `insidefthe lid Aand extends nearly across'the lid in the preferred form, leaving the spaces 24 between-its side edges and the inner folds 'i 20 at the sides, so that the box ean pass over they top edges of ytheV sides 1l .of the body portion, the sheet. 23 being arranged at its rear edge25 so that it is substantially pivotal to the top edge yof the back 12,to`

which it is hinged asuitable hinge, usually in boxes of-cardboard by a strip26 of` linenrror tough. fabric, the fend of this hinged strip being secured to the'cover also by means of strips 27 ofcardboard, which' kare thick enough to :take up lthe yspace between the upper part of thecover vandthe end 25 of the sheet 23, so that the movement backward of the lid is1 possibleffby such open position since it is beyond theV center of the swinging movement and Y reason of the; point at which the swinging `takesplace, and therear; Yproj ectingl part l28= ofthe .coverv acts,as a rstopandwthellid 105 naturally has a tendency to rest against the y part 28, which acts as a stop.

' 110 The outer or forward end of the sheet 23 I is Vfree and spaced apart, from the insideA of the cover, and in order to provide this spacing, and also to give the required spring combined with stiffness, the end 29, which is the forward end of thesheet, is bent so as to .be spaced from the side top face of the cover and is preferably fastened by pasting o'r otherwise, as at 30, to prevent movement of the sheet itself. The free end 2Q of the sheet andthe forward wall 3l of the cover are spaced-so that they will receive the topv edge 32 of thefront wall of the body portion.V As stated herenbefore, the spaces and dimensions of these parts are slightly exaggerated to bring outmore clearly the function of this arrangement, and in Fig. 3 the closed lid shows vthat the free end 29 on the inner side of the cover frictionally engages the front wall of the body portion von'the inside, and the front wall 3l of the cover engages the front'wall of the body `portion onthe outside, and the lid does not accidentally come open but is held shut by this frictional engagement. Y

v It will also be noted that the free end 29 'is below the top edge'of the cover and below Vthe axis ofthe hinge; in other words, below the axis of the point on which the cover swings, s0r that any movement upward of f the cover tends to swing the lid slightly outward on its upwardinovement as is traveling through the lower arc of a'y circle with the hinge of the lid asits center, but Vthis arrangement is permittedthrough the spring or slight elasticity ofthe end 29 of the ,heet 23, thisbeing usually made of cardboard. v

It willV be noted invFig. 3 that the lid is vshown at an incline, but this incline is exaggerated, Aas the box injreality has its lid more nearly level, but in order to emphasize the movement of the, free end 29'below the top edge ofthe vbody portion, which is .usually the level on which the cover swings,

the. space is enlargedm'in the drawing so as to make this point clear, although it will be understood that,if desired, the. box canbe made just illustrated, with a noticeable inclination of the cover.

l Itl will thus be seen that I haveV devised ajbox ywith an overhanging cover that is durable, the cover and the base portion haviner stiffened and braced edges, andlin which Vthe-sides and the'front wallfof the body portionare seated into the space on three sides of the cover between the outer edgesY of the sheet 23 and the inner folds 20, this space 24 receiving the top edges of these "Walls and making a tightY closure, which is `wall, the front edge of the sheet and V.the

fold being spaced to receive the top edge yof the front wall, the front edge ofthe sheet being free so as to Ahave a limitedresiliency s0VY that vits `friction against thefront wall increases as it is'movedfrom `its closed position toward the top edge of the front wall.

2. A box having side walls and having a coverformed ofa top having' itsedges turned inwardly atan angle and then back to the top Vto. form inner folds -'to fit .over the, outside of the walls, a hinge securing the cover to the top edge of the rear wall,

and a resilient lip spaced from the inside of the top to engage the inner sidefof the wall'below theftop edge thereof and below the level of the hinge when the cover lis shut.

3. A box having side walls and having a cover formed of a to havin its edO'es turned inwardly at an angle and'the'n back tothe top to form inner Vfolds to litl over the voutside of the walls, a hinge'securing the cover to the top 'edge ,of the rear wall,

and a sheetsecured to the Vi'nsidefof the'topA near the free end thereof and to the cover at the point where it is hinged, the end of the sheet at the free end of the cover'being bent so as toA be spaced therefrom and form a resilient lip to engage the inner face'of the front wall below the level of the hinge when the cover is'shut.

Ll. Abox'having side walls and having a cover formed Aof a top'havingV its edges turned inwardly at an angle and then` back totheftopvto form vinner folds to lit over the outside of the walls, a hinge securing thecover at the juncture of one of the inner folds with an inwardlyturned'edge 'to the topedge of the rear wall of thebox, whereby l the inwardlyl turned edge acts .as a stop when the lid is opened andA thus acts to hold the lid in a rearwardly inclined position on its hinge. Y

In testimony that I claim the foregoing I have hereto set myhand this 26th day .of June,1919. 1 i
